I'm not sure if this was posted here already. I didn't see it. Teacher Express is having their dollar days and there is a code which will allow you to get ten ebooks for free. I had the hardest time the last couple days with it working, but they extended the sale and today I got it to work. The coupon code is 10THANKS but for some reason the system only seems to accept the code if you add an item marked down to free. So I added ten of the dollar days items to my cart, plus an item that was regularly $3 but marked down to free. If you don't do that step it doesn't seem to want to accept the coupon code. Hope that helps someone. I'm not sure how much longer they'll continue the promotion so I'd hurry.
